Natural selection favours genes that increase an organism's ability to survive and reproduce.
This would appear to lead to a world dominated by selfish behaviour. However, cooperation …

Spatial self‐structuring has been a focus of recent interest among evolutionary ecologists.
We review recent developments in the study of the interplay between spatial self‐structuring …

Allee effects are (broadly) defined as a decline in individual fitness at low population size or
density. They can result in critical population thresholds below which populations crash to …

Willingness to lay down one's life for a group of non-kin, well documented historically and
ethnographically, represents an evolutionary puzzle. Building on research in social …

Recent decades have witnessed an explosion of theoretical and empirical studies of sex
allocation, transforming how we understand the allocation of resources to male and female …

Humans update their social behavior in response to past experiences and changing
environments. Behavioral decisions are further complicated by uncertainty in the outcome of …

Ecology is a fundamental driving force for the evolutionary transition from solitary living to
breeding cooperatively in groups. However, the fact that both benign and harsh, as well as …

There has been extensive theoretical debate over whether population viscosity (limited
dispersal) can favour cooperation. While limited dispersal increases the probability of …

In a recent paper, Traulsen and Nowak use a multilevel selection model to show that
cooperation can be favored by group selection in finite populations [Traulsen A, Nowak M …

In natural populations, dispersal tends to be limited so that individuals are in local
competition with their neighbours. As a consequence, most behaviours tend to have a social …
